Description

Válvula de seguridad para depósitos de combustible.Safety valve for tanks fuel.

Objeto de la invenciónObject of the invention

La presente invención se refiere a una válvula de seguridad para depósitos de combustible, especialmente aplicable a depósitos de vehículos de gasóleo, con el fin de evitar el llenado del depósito con gasolina.The present invention relates to a valve safety for fuel tanks, especially applicable to deposits of diesel vehicles, in order to avoid filling the tank with gasoline.

Antecedentes de la invenciónBackground of the invention

Las estaciones de servicio dedicadas al suministro de carburante para vehículos disponen de surtidores específicos de gasolina y de gasóleo, siendo el usuario del vehículo el que elige el tipo de carburante a utilizar.The service stations dedicated to Fuel supply for vehicles have suppliers specific to gasoline and diesel, being the user of vehicle that chooses the type of fuel to use.

El problema que se plantea, principalmente en el caso de los conductores noveles y de usuarios de vehículos de alquiler, es el riesgo de equivocación a la hora de elegir el tipo de carburante, gasolina o gasóleo, ya que cuando se añade gasolina en un depósito de gasóleo, o cuando se añade gasóleo en un depósito de gasolina se produce una situación de riesgo, dado que el uso del combustible indebido puede acarrear averías considerables del motor y sus partes mecánicas, además de una costosa reparación que requiere el vaciado del combustible y la limpieza de las canalizaciones, bombas de presión, filtros, inyectores y otras piezas del sistema de alimentación.The problem that arises, mainly in the case of novice drivers and vehicle users of rent, is the risk of mistake when choosing the type of fuel, gasoline or diesel, since when gasoline is added in a diesel tank, or when diesel is added in a tank of gasoline a risk situation occurs, since the use of improper fuel can lead to significant engine failures and its mechanical parts, in addition to an expensive repair that it requires the emptying of the fuel and the cleaning of the pipes, pressure pumps, filters, injectors and others Power system parts.

Así, las mangueras de los surtidores están dotadas de unos boquereles, de diferente diámetro para la gasolina y para el gasóleo, y a su vez las bocas de entrada de los depósitos de combustible están dimensionadas de acorde a estos diámetros. De esta forma no es posible echar gasóleo en un depósito de gasolina, porque el diámetro del boquerel correspondiente es sensiblemente mayor y no entra.Thus, the hoses of the pumps are equipped with nozzles, of different diameter for gasoline and for diesel, and in turn the deposit inlets of fuel are sized according to these diameters. From this way it is not possible to put diesel in a gas tank, because the diameter of the corresponding nozzle is substantially older and does not enter.

Sin embargo si es posible echar gasolina en un depósito de gasóleo, por lo que sigue existiendo el citado riesgo para los vehículos cuyos motores consumen gasóleo.However, it is possible to add gasoline to a diesel tank, so the aforementioned risk still exists for vehicles whose engines consume diesel.

Descripción de la invenciónDescription of the invention

La válvula de seguridad para depósitos de combustible, objeto de esta invención, está diseñada para evitar que se llene con gasolina un depósito de un vehículo de gasóleo, ya sea de forma accidental o por negligencia, bastando para ello con colocar dicha válvula en el conducto o boca de entrada del depósito.The safety valve for tanks fuel, object of this invention, is designed to prevent that a tank of a diesel vehicle be filled with gasoline, since either accidentally or negligently, enough for that place said valve in the duct or inlet of the Deposit.

La válvula comprende un cuerpo tubular, abierto por sus extremos, y destinado a posicionarse de forma ajustada en el interior de la boca del depósito de combustible; definiendo dicho cuerpo tubular un pasaje en cuyo interior se encuentran alojados: un elemento de obturación, movible entre una posición de apertura y una posición de cierre; un tope de retención del elemento de obturación en la posición de apertura, siendo dicho tope de un material soluble en gasolina e insoluble en gasóleo, y un elemento elástico que actúa sobre el elemento de obturación y provoca su desplazamiento hacia la posición de cierre cuando se disuelve el tope debido al repostaje inadecuado con gasolina.The valve comprises a tubular body, open at its ends, and intended to position itself tightly in the inside of the fuel tank mouth; defining said tubular body a passage inside which are housed: a shutter, movable between a position of opening and closing position; a retention stop of the sealing element in the open position, said being top of a material soluble in gasoline and insoluble in diesel, and an elastic element that acts on the sealing element and causes its movement to the closed position when dissolves the stop due to improper refueling with gasoline.

En la posición normal de uso la válvula está abierta, permitiendo el paso del gasóleo por su interior hacia el depósito. Sin embargo, cuando se intenta repostar con gasolina, se produce la disolución rápida del tope y se cierra la válvula automáticamente por la acción del elemento elástico mencionado anteriormente.In the normal position of use the valve is open, allowing the passage of diesel oil inside to the Deposit. However, when trying to refuel with gasoline, it produces the rapid dissolution of the stop and the valve closes automatically by the action of the elastic element mentioned previously.

Al cerrarse la válvula, la gasolina que suministra el boquerel se acumula rápidamente en el interior del cuerpo tubular de la válvula, activando el sistema de seguridad de dicho boquerel, el cual deja de suministrar gasolina. La pequeña cantidad de gasolina que pueda haber caído en el depósito se diluye sin problemas con el gasóleo de relleno, evitando la avería del vehículo.When the valve closes, the gasoline that supplies the nozzle quickly accumulates inside the tubular valve body, activating the safety system of said nozzle, which stops supplying gasoline. The little girl amount of gasoline that may have fallen into the tank is diluted without problems with the diesel filling, avoiding the breakdown of vehicle.

En caso de estar realizando un llenado manual, por ejemplo mediante una garrafa, el bloqueo de la válvula evita también la entrada del líquido, rebosando dicho líquido hacia al exterior cuando alcanza la cota de la boca de llenado.If you are filling manually, for example by means of a canister, the blocking of the valve prevents also the entrance of the liquid, overflowing said liquid towards the outside when it reaches the level of the filling mouth.

El elemento de obturación es preferentemente tipo mariposa y se encuentra articulado por su zona media sobre el cuerpo tubular mediante un eje transversal.The sealing element is preferably type butterfly and is articulated by its middle area on the tubular body by a transverse axis.

De acuerdo con la invención el cuerpo tubular presenta en su extremo posterior una pluralidad de prolongaciones laminares dispuestas de forma divergente, configurando un embudo que facilita el posicionamiento centrado del cuerpo tubular en el conducto de entrada del depósito de combustible y que permite orientar el flujo de combustible entrante hacia el interior del cuerpo tubular. Esto asegura el correcto funcionamiento de la válvula, ya que el paso de fluido por el interior del conducto mojando el tope, está asegurado al repostar el depósito.According to the invention the tubular body it has a plurality of extensions at its rear end laminators arranged divergently, configuring a funnel which facilitates the centered positioning of the tubular body in the fuel tank inlet duct and allowing orient the incoming fuel flow into the interior of the tubular body This ensures the proper functioning of the valve, since the passage of fluid through the inside of the duct wetting the top, it is secured when refueling the tank.

A su vez, el cuerpo tubular presenta en su extremo posterior una tira alargada que remata en un aro abierto de sujeción. Esta tira queda lateralmente próxima a las paredes del conducto de entrada de combustible y el aro queda fácilmente accesible en la boca del depósito. Su expansión dentro de la boca de llenado permite su ajuste óptimo y evita que se introduzca excesivamente en el conducto citado.In turn, the tubular body presents in its rear end an elongated strip that ends in an open ring of subjection. This strip is laterally close to the walls of the fuel inlet duct and the ring easily fits accessible at the mouth of the tank. Its expansion inside the mouth of filling allows for optimal adjustment and prevents it from entering excessively in the mentioned duct.

Dicho aro abierto comprende un asa abatible, de forma aproximadamente semicircular, para facilitar la extracción de la válvula. El asa, preferentemente metálica, queda a un lado en posición inoperante, evitando toda molestia al introducir el boquerel de llenado o el tapón de cierre en la boca de llenado. A su vez, es fácil disponer el asa en una posición operativa, sobresaliendo hacia el exterior, para permitir la extracción la válvula simplemente tirando de ella. El aro abierto presenta en su cara interior, al menos, una prominencia para el apoyo estable del asa en la posición abatida o inoperante.Said open ring comprises a folding handle, of approximately semicircular shape, to facilitate the extraction of The valve. The handle, preferably metal, is set aside in inoperative position, avoiding any discomfort when entering the filling nozzle or closure plug in the filling mouth. TO in turn, it is easy to arrange the handle in an operative position, protruding outward, to allow removal of the valve simply by pulling it. The open hoop presents in its inner face at least a prominence for the stable support of the handle in the down or inoperative position.
